The fOSSa 2010 conference in Grenoble did a good job to prove (since it’s still sorely needed, see conclusions below) that Free/Open Source Software (FOSS) isn’t some unreliable toy for amateurs.FOSS for the Software and Web Industry I have already described in other articles the lessons that ALL managers could have learned at fOSSa and its coverage of the relationships among FOSS, education and environmental sustainability. Besides that, there were lots of interesting, if highly technical talks (I really want to study GeoBi for example).
